Specification of Letters Patent. I Patented 69$, 1'? 1916.

Application filed September 1, 1915. Serial No. 48,457.

To all whom it may concern:

Be it known that I, MERTIE THmns, a citizen of the United States ofAmerica, residing at Wichita, in the county of Sedgwick and State ofKansas, have invented certain new and useful Improvements in Air-CoolingDevices, of which the following is a specification.

My invention relates to means for artifi cially cooling air, and theobjects contemplated thereby are the provision of a device in whichmaterial having the characteristics of absortion and capillaryattraction is em ployed as a medium for carrying a cooling liquid insuch manner that air at a high tem perature, upon impinging thereagainstwill be cooled and slightly humidified; to pro vide a device of thischaracter'which is extremely simple in construction and arrangement, andwhich accordingly may be manufactured at a minimum cost; to provide adevice which makes it necessary for the circulating air to traverse ortake a tortuous course, thereby subjecting the air to the maximumcooling surface; and to provide a device which is thoroughly braced andre inforced at all points so as to effectively resist strong currents orblasts of air.

To the accomplishment of the recited objects and others coordinatetherewith, the preferred embodiment of my invention resides in thatconstruction and arrangement of parts hereinafter described, illustratedin the accompanyingdrawings, and embraced within the scope of theappended claims.

In the drawings :Figure 1 is a vertical sectional elevation showing mydevice as adapted to the frame of a window. Fig. 2 is a perspective viewpartly broken away, of the device removed; and Fig. 3 is a transversesection of the air cooler as shown in Fig. 2.

Referring more particularly to the drawings for a detailed descriptionof my invention the numeral 1 designates a frame comprised of verticalside members 2-. an upper reservoir 3 and a lower receiving chamber 41.The reservoir 3 is provided with a supply pipe 5 equipped with asuitable valve 6, and also carries a cover or closure, as 7. Arranged instaggered relation along the bottom of the reservoir 3 are a series ofsmall pin openings 8, and eXteriorly of the bottom in alinement withthese openings are a plurality of depending bails 9 which serve tosupport the vertical absorbent tapes or strips 10. These tapes aredoubled upon themselves or. fashioned into endless bands, the vertlcalparallel portions of which are rela tively close together, and at theirlower ends they are threaded through the slots 11 in the upper portionof the receiving chamber 4:, the slots being made sufliciently large sothat their walls will not contact with the said tapes. In order toeffectively brace these strips and render them secure against flapping Iprovide a series of transverse noncorrodible wires or elements 12 whichare stitched with respect to the strips, as at 13, and sustained atopposite ends by the vertical side members 2 of the main frame portion.

By the way of a single illustration, I have shown my invention fitted'to a' window frame 14:, as exhibited in Fig. 1, although'it will beunderstood that the principle of the device is applicable to variousother uses. In this case I may provide an outlet 15 leading from thereceiving chamber 4 and designed to supply a similar reservoir as 16located in the window frame 17, which is just below the uppermost windowframe 14:, thereby carrying out the idea of continuity of arrangementwhich obviously would permit of equipping all the windows of largeotlice buildings, hospitals, etc. with facility.

In operation, the valve 6 connected to the main supply pipe 5 is openedthereby permitting a suitable quantity of cool water to enter thereservoir 3. This water trickles through the small pin openings 8 in thebottom of the reservoir and is precipitated upon the upper ends of theseveral endless bands of tape 10, each series of openings serving tofeed the two portions of each strip. The

'moistening of these bands is manifestly accelerated by reason of theprinciple of capillary attraction coupled with gravity, and it followsthat in a veryshort time the entire length of the several tapes will bethoroughly saturated with water. Upon the air, which is presumably of ahigher temperature than the water, impinging against the surfaces of themoist tapes and being obliged to traverse 'a' well defined zig-zagcourse, it will readily be seen that the temperature of the air whenissuing through the opposite side of my device will be lowered. While-itis true that the natural course of the air is interrupted owing to theangular disposition of the tapes, it is likewise true that the air isnot subjected to any filtering process,

which later would be likely to cause a clog ging of the interstices ofthe tapes. By reason of the relatively close disposition of the parallelportions of the individual tapes, the air entering therebetween will becaused to intimately contact with the moisture and is thereby cooled andslightly humidified. The spaces between the individual endless bands oftape are greater than the spaces between the parallel portions thereofso that too much moisture will not be taken up by the air as it passestherethrough.

It should be understood that in its broader aspect the inventioncomprehends the em,- ployment not only of the various means described,but of equivalent means for performing the recited functions.

While the arrangement shown is thought at the present time to bepreferable, it is desired to reserve the right to effect suchmodifications and variations thereof as may come fairly within the scopeof the appended claims.

1. In a device for cooling air, the combination of a reservoir having aseries of outlets, a receiving chamber, and two rows of bands ofabsorbent tape having their upper ends disposed beneath said outlets andadapted to catch the drippings therefrom,

while the lower ends of said bands terminate within said receivingchamber, the bands of one row being arranged in pairs and atsubstantially right angles to each other, and the bands of the other lowbeing parallel to each other and disposed in close proximity to theangle of each pair of bands in the first mentioned row.

In a device for cooling air, the combination of a reservoir having aseries of outlets, a depending bail beneath each series of outlets, areceiving chamber, and two rows of bands of absorbent tape having theirupper ends connected to said bails and adapted to catch the drippingsfrom said outlets, while the lower ends of said bands terminate withinsaid receiving chamber, the bands of one row being arranged in pairs andat substantially right angles to each other, and the bands of the otherrow being parallel to each other and disposed in close proximity to theangle of each pair of bands in the first mentioned row.

In testimony whereof I afliX my signature in the presence of twowitnesses.
